I'm looking to book from an Enterprise neighborhood location, and reserving a pickup will be cheaper than compact car. But I don't need/want a pickup, and I doubt any location in the city actually carries a pickup. If they don't have it, will they assign me a car instead, at the same rate?

In the past I've had situations where they didn't have my reserved car class (another neighborhood location), so they had upgraded me to Full Size cars. But they also charged an upgrade fee for it, which was shady, but only a few bucks more each time, so I didn't bother complaining. The difference this time is more than $40, so I'd rather be sure what their policy is in case pickup or similar class vehicles aren't available.

Any help is appreciated.
